New York Yankees vs Seattle Mariners Prediction and Picks, August 12, 2026

As the New York Yankees gear up to face the Seattle Mariners, the stage is set for a compelling showdown. The Yankees have been firing on all cylinders lately, bolstered by a lineup that’s been raking at home. With a potent mix of power hitters, they’ve averaged over five runs per game at Yankee Stadium, making it a daunting task for visiting pitchers. On the hill for New York, their ace has been nearly untouchable, boasting a sub-3.00 ERA and a strikeout rate that leaves batters guessing. Meanwhile, the Mariners have struggled against top-tier pitching, often flailing at the plate. Given the Yankees’ recent form and their strong home record, it’s hard to see the Mariners keeping pace. With the Yankees likely to win by at least two runs, taking them on the alternate run line at -1.5 feels like a savvy move. Expect the Bronx Bombers to deliver a decisive victory.

Trent Grisham (SDP) Over 0.5 Hits+Runs+RBIs (-294)

As the Yankees take on the Mariners, keep an eye on Trent Grisham; his recent form suggests he’s primed for a standout performance. Grisham has been increasingly comfortable at the plate, showcasing his ability to get on base consistently. With the Yankees' lineup packed with power hitters, the chances for him to score runs or drive in RBIs rise significantly when the opportunities arise. Seattle has been prone to allow runs, especially against right-handed pitchers. Given their struggles with fastballs, Grisham’s knack for making contact could see him register at least one hit. Plus, with the Yankees’ home-field advantage and their potent offense, the chances of Grisham crossing home plate or driving one in are elevated. With an implied probability hovering around 74.6%, betting on him to go over 0.5 hits, runs, or RBIs feels like a savvy move today.

New York Yankees vs Seattle Mariners: New York Yankees +1.5 (-233)

As the Yankees host the Mariners, there’s a compelling case for backing New York on the alternate run line of -1.5. The Bronx Bombers have been flexing their muscles lately, showcasing a potent offense that’s averaged over five runs per game this month. With a lineup that boasts players in red-hot form, including a few who have been tearing the cover off the ball, the Yankees appear primed to put up a crooked number. On the mound, their ace has been a force, striking out batters at an impressive rate while limiting hard contact. Seattle, meanwhile, has struggled against left-handed pitching, which could spell trouble against the Yankees’ southpaw. Given these trends, coupled with New York’s strong home record, the Yankees not only have the momentum but also the statistical backing to cover the run line. Expect the Bronx to roar loud and proud tonight.

New York Yankees vs Seattle Mariners: Under 8.5 Total Runs (+100)

As the New York Yankees host the Seattle Mariners, all signs point to a low-scoring affair. The Yankees have thrived on their pitching prowess, boasting a top-tier rotation that has kept opponents at bay—especially at Yankee Stadium. Recent outings show their starters consistently limiting runs, which should be crucial against a Mariners lineup that has struggled to generate consistent offense on the road. On the other side, Seattle's pitching has quietly emerged as a strength, with their starters showcasing impressive strikeout rates and solid ERAs in recent weeks. With both teams in a groove of late-inning pitching dominance, the under seems particularly enticing. Considering the Yankees' recent trend of games hitting below the total and the Mariners' own offensive inconsistencies, betting on the under at 8.5 feels like a savvy play. Expect a game defined more by strong pitching than by fireworks at the plate.

New York Yankees vs Seattle Mariners: Under 8.5 Total Runs (-106)

As the Yankees host the Mariners on August 12, we’re looking at a matchup that could lean heavily on the pitchers’ prowess. The Yankees have been rolling out a pitching staff that thrives in tight situations, boasting a strong ERA that has tightened up in the last few weeks. Meanwhile, the Mariners, while explosive at times, have struggled against lefties, which plays right into the Yankees’ hands with their left-handed ace on the mound. Recent trends highlight both teams’ tendency to keep games lower-scoring. The Yankees have nudged towards the under in several of their last outings, while the Mariners have also found themselves in a few low-scoring affairs, particularly on the road. With both offenses potentially stalling against quality pitching, taking the under at 8.5 runs feels like a savvy play. Expect a battle on the mound that may just keep the scoreboard quiet.

George Lombard Jr. Over 0.5 Hits+Runs+RBIs (-233)

As the Yankees gear up to face the Mariners, keep an eye on George Lombard Jr. He’s been a rising star, showcasing impressive plate discipline and power. Recently, he’s been on a tear, consistently finding gaps and driving in runs. With the Yankees’ potent lineup supporting him, Lombard has a prime opportunity to capitalize against Seattle’s pitching, which has struggled at times, especially against left-handed hitters. The Mariners' bullpen hasn’t exactly been a fortress this season, allowing too many base hits and runs. Lombard’s aggressive approach and ability to make contact suggest he could easily surpass the 0.5 mark for hits, runs, or RBIs. Given his current form and the recent trends favoring the Yankees’ offense, betting on Lombard to deliver at least one productive hit seems like a savvy play. Expect him to shine under the bright lights at Yankee Stadium tonight.
